The NEMO Arms Blue collar rifle. That is the Pratka model OMEN. The Pratka squares off directly with .308 AR rifles. This model gives you a shorter, lightweight barrel and lightweight stock. This is a no frills rifle at first glance, but it has all of the upgrades that an operator wants, like a match trigger, billet receivers and muzzle brake. This isn’t your typical black rifle. The Pratka is harder hitting than any high-end .308 ARs and competitively priced. Shoot one for yourself and experience first-hand an advanced evolution in military-grade ARs.
